Application led July S, 1914. Serial No. 849,821.v i Y S To all whom itmay concern.'

Be it known that I, CHARLES O. ANDER- soN, a citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in Driers,

Tempering-Heaters, and Cookers, of which the following is aspecilication. Y

My present invention pertains to .improvements in driers, temperingheaters and cookers, more particularly those which are adapted to handlesuch materials ascorn, cotton seed, brewers grain, cotton-seed meats andthe like. vThe apparatus is especially suitable for use in connectionwith material which is to be subjected to heat for a considerable periodof time, and in its simplest form is shown in the annexed drawings,wherein: Y Y Y Figure l is a longitudinal sectional lelevation of theapparatus; Fig. 2 anelevation of the discharge end of the same, partsbeing broken away; and Fig. 3 a vertical sectional view, taken on theline 3 8 of Fig. 1, and looking toward the feed end of the machine.

The main object of the invention is tov provide a readily formed andsectional ap- A paratus for drying wet material wherein the same will besubjected to a relatively long period of drying and caused to passgradually from the feed end of the machine to the discharge end thereof,the feed and discharge being continuous afterV the apparatus is onceloaded. The apparatus is also applicable for the purpose of cooking, andparticularly for cooking cotton-seed meats preparatory to placing themin a hydraulc press. A

I vrTheinvention is in a sense 'an improvement upon the .apparatus setforth in the .application filed in the name of 'Frank B.

Anderson under date of July 8, 1914, ySerial No. 849,822. v j

Under the present construction it is designed to produce a trough from anumber of similar units, which may be readily formedV and easilyjassembled. and/the machine lengthened out or shortened up, as may berequired, by merely including or removing certain of the sections.V Y

` i A. further object of the construction is to so form the sections ofthe apparatus as to produce a series of pockets or' the like betweenwhich the stirrers or agitators work, and over the walls of which thematerial of the apparatus.

Vin the apparatus is fed from the intake to The main ,body ofthestructureV may be said to comprise a seriesy of sections or cast.- ings1, all alike in form, and a head 2 at the feed end Vand the dischargeend of the machine, which heads and sections, together with a xed coverplate Aorlnember 3 and hinged sections, or doors 4, produce a troughthrough .which the material is traversed. The sections 1, when viewedfrom the end or .cross-section, are substantially crescentshaped inform, the side walls 5 andati-icon'- verging toward each other at theirupper sides the discharge end v i and preferably formed with an inclined`discharge face 7 the inclination being toward the discharge end of theapparatus. froml short vertically -disposed walls 8, which in turn areformed integrally with the outer wall 9, said walls forming a space orchamber 10 into which the heating medium may be introduced through apipe, as 11, connected with a manifoldv 12..` Apipe Thewalls 5andextendupwardly i 13g-extends from the lowerend ofthe chamber 10 andconnects with a manifold or main 14. Thus each section is hollow and theconverging'walls of the adjacent sections form pockets, as 15, orinother words, there is produced a which are separated by a series ofupstanding hollow heated walls, the pockets occupying a position in thebottom and rear-side of the structure. v j

Thevarious sections are providedv with series of inclined pockets lugs16, disposed around the same, and tiebolts are passed therethrough, andthrough corresponding members upon the heads, so that the sections willbe drawn tightly together and a close union effected between the headsand the adjacent walls 8 of the various sections. The structure thusbuilt up will preferably4 be secured upon pedestals 17, as best shown inFigs. 2 and 3.

Normally and while the v.machine is in operation the doors are designedto be kept closed,'and to this end clamps 18 are employed.

Extending through and journaled in the heads is a shaft 19, and mountedupon said shaft are a series of arms 20, each arm car- 1 rying at itsouter end a paddle or blade 21, one end of which is curved to conformto-the curvature of the adjacent wall 5 or 6, as the case may be, andpreferably a pair of such arms and blades (which may be termed stirrersor agitators) are secured upon the shaft so that there will be two suchstirrers working in each pocket 15. At the discharge end of the machinethe pocket has but half the dimensions of the intermediate pockets, andconsequently but one stirrer is shown therein.

The head2 at the discharge end of the machine is provided with anopening 22, Figs. l and 2, said opening being formed at one side of thecenter. An adjustable gate 23 moves over said opening and controls thedischarge of the material from the machine, the material flowing overthe upper edge of the gate and into a spout 24.

The shaft 19 is driven by means of a large gear wheel 25, which receivesits power from a pinion 26. rIhe shaft alsoy carriers` a sprocket wheelabout which passes a sprocket chain 27, said chain imparting motion to asprocket wheel 28, mounted upon a shaft 29. Said shaft carries aneccentric 30, Fig. 2, which in turn aetuates a pitman 31, connected tothe swinging bottom 32 of a feed device. The hopper of such device isdenoted by 33, and is provided at one side with an adjustable gate 34,so that the amount of material which is fed from the hopperV anddischarged into the machine may be regulatedl as desired. 'Ihis is awell-known form of feed mechanism, but any other construction may-besubstituted therefor.

The member 3 will preferably be provided with an off-take pipe 35,through which the steam or other vapors driven ofi' from the materialwill be withdrawn.

rllhe operation of the apparatus is substantially as follows: Themachine being set 1n operation and the` heat being supplied to thechambers 10 of the various sections 1, material is fed in at the feedend of the machine and will be distributed throughout the apparatusthrough the action of the agitators. In other words, the material willseek its own level, and be evenly distributed throughout the machineuntil it reaches a height equal to that of the upper edge of thedischarge gate,` when it will iiow over said gate and out through thespout 24 as fast as it is fed into the machine by the feed mechanism.Being constantly agitated and stirred, it comes into contact with theheated surface of the various sections, and the heated material iscommingled with the wet material and thereby the water is driven off andpasses out through the pipe 35. Being constantly moved into contact withthe heated surface andintermiXed or intermingled throughout the machine,the material becomes thoroughly dry and a relatively small apparatus maybev used as compared with a structure in which the material is merelyfed through the machine 1'n contact with a heated surface. rIhematerial, owing to the action of the agitators, willassume an angle ofrepose in the apparatus substantially in line with the upper end of thesections 1, or in other words, will come to repose at the angleindicatedby the lines A-A in Fig. 3. Should it be desired to dischargethe apparatus quickly, this may be readily accomplished by throwing thedoors a upwardly, and reversing the direction of movement of theagitators, which will then sweep the material from the inclined pockets,the tendency of the material to gravitate contributing to the readydischarge thereof.
